Abstract
A method for the preparation of steel sheets for fabricating a welded steel blank is provided. The method includes a step of removing at least part of the first and second metal alloy layers in first and second peripheral zones of pre-coated steel first and second sheets, respectively, by simultaneously ablating the first and second precoatings in the first and second peripheral zones of the pre-coated steel first and second sheets to define first and second ablation zones, the first and second peripheral zones being zones of the first and second principal faces closest to the median plane and located on either side of the median plane.
